John McCain announced he is returning to Capitol Hill on Tuesday, nearly a week after his office announced he was diagnosed with brain cancer.

"Senator McCain looks forward to returning to the United States Senate [Tuesday] to continue working on important legislation, including health care reform, the National Defense Authorization Act, and new sanctions on Russia, Iran and North Korea," a statement from McCain's office read.
